In 2011, KTH Royal Institute of Technology adopted a policy on scientific publishing geared towards creating full accessibility of research output. The main objective of this report is to assess the long-term effects of this policy. To that end, we collected and analysed publishing data at KTH, along with related expenditures. More specifically, we track changes in counts and shares in open access publishing over the past decade, as well as describe trends at multiple levels of analysis, ranging from conference proceedings to journal article publishing at KTH and its affiliated schools. Additionally, we provide insight into both the past and present state of open access publishing, and briefly discuss the future of open access publishing at KTH. This report is aimed towards all interested in publishing practices at KTH. Throughout this report, we use concepts and definitions derived from prior year documentation and analysis of open access publishing at KTH.

Open Access publishing (OA) has been promoted by public institutions and research communities in many countries for some years now. Various categories encompassing different types and practices of OA are precisely described in definitions that now seem to be well-established. OA status is now available as part of a publication's metadata in all major publication databases, while some data sources such as Unpaywall are specifically dedicated to this type of information.

At KTH, we monitor and document the effects of this shifting landscape and of policies promoting OA by means of an annual OA report focused on scientific publications by our researchers. This allows us to observe potential effects of KTH policy changes and to identify areas that the KTH management or the KTH library could support or strengthen. To this end, we collect the OA status (open, closed) and OA type (gold, diamond, hybrid, green) from Unpaywall for several publication types (journal articles, conference proceedings, theses, book chapters) and aggregate these data both for KTH as a whole and for each of its five schools. We also identify the journals in which KTH researchers publish the most and calculate the OA proportion of KTH publications in these. Finally, we take a look at the evolution of publishing-related costs for KTH and KTH schools and relate them to changes in the university's publishing policy.

Results show that the OA share of KTH peer-reviewed publications has been globally increasing since 2011, strongly so for theses and journal articles. This is mainly due to the increase of gold and hybrid OA, despite the fact that journals where KTH authors publish the most are still mainly subscription-based. The increase in OA share is less pronounced for conference proceedings but nonetheless steady. A diversity of publishing practices in different research areas is revealed by the different OA publishing patterns at the different KTH schools. An overall increase in Article Processing Charges (APC) can be observed, related to both the increase of the number of hybrid and gold OA publications and to the implementation of new transformative agreements with several publishers.

We discuss the consequences of the current university policy and compare it to alternative policies supporting OA while limiting the increase of publishing costs. We also reflect upon the extent to which researchers can be guided towards better OA practices and the role a university library may play in the process. Considering the questions of sustainability in a foreseeable future and of equity in the scientific publishing landscape paramount, we strongly value input from various actors within open science communities in order to build a sound reference framework for OA-supporting policies.

In this report, shares and trends of open access publishing at KTH are analysed starting from 2011, the year when a policy for scientific publishing at KTH was implemented.1 The report is for anyone interested in how open access publishing at KTH has developed over the years. It can also be used as a basis for planning on how to proceed with the work on open access at KTH.

During 2011, a policy for scholarly publishing was implemented at KTH.1 The policy states that researchers at KTH should strive to publish open access, either through well-reputed open accessjournals or by self-archiving in KTH publication database DiVA. Publications published by KTH – i.e dissertations, bachelor and master theses, reports – are to be self-archived in DiVA as a general rule. In this report, shares and trends of open access publishing at KTH are analysed starting from the same year the policy was implemented, in 2011. A report that analyses open access at KTH will then be released annually.

Syftet med projektet har varit att undersöka hur stor del av den svenska forskningen som har publicerats open access under publiceringsåret 2011. Vi har studerat den totala andelen open access-publikationer, både så kallad guld och grön open access, dels nationellt och dels per lärosäte. Vi har också velat undersöka hur stor andel av artiklarna i vårt underlag som skulle kunna parallellpubliceras enligt SHERPA/RoMEO, men där så inte skett. Ett vidare syfte har även varit att ta fram metodik för att skapa förutsättningar för framtida mätningar av svensk OA-publicering.

Under 2013 genomfördes en studie över andelen open access (OA) i Sverige. Projektet finansierades av Kungliga bibliotekets program Openaccess.se. I undersökningen, som använde SwePub som index, studerades hur stor del av svenska forskningsartiklar med publiceringsår 2011 som är OA. Analysen gäller dels andelen guld och grön OA, men också hur stor del av de publicerade artiklarna som skulle kunna parallellpubliceras enligt förlagens villkor. Analysen visar att andelen OA-artiklar som publicerades under år 2011 uppgick till cirka 17 procent, varav guld OA 10 procent och grön OA 10 procent. Detta indikerar ett överlapp av artiklar som är både guld och grön OA på cirka 3 procent. Räknar man även in så kallat fördröjd OA så uppgår den totala mängden OA-artiklar år 2011 till uppemot 25 procent. Resultatet visar vidare att ytterligare en stor mängd artiklar skulle kunna parallellpubliceras enligt informationen i Sherpa/RoMEO.
